lockInterruptibly()

• lockInterruptibly()：相當(dāng)于tryLock(long time, TimeUnit unit)把超時時間設(shè)置為無限，在等待鎖的過程中，線程可以被中斷

unlock()

• unlock()：解鎖

package lock.lock;import java.util.concurrent.ThreadPoolExecutor; import java.util.concurrent.locks.Lock; import java.util.concurrent.locks.ReentrantLock;public class LockInterruptibly implements Runnable {private Lock lock = new ReentrantLock(); public static void main(String[] args) {LockInterruptibly lockInterruptibly = new LockInterruptibly();Thread thread0 = new Thread(lockInterruptibly);Thread thread1 = new Thread(lockInterruptibly);thread0.start();thread1.start();try {Thread.sleep(2000);} catch (InterruptedException e) {e.printStackTrace();}thread1.interrupt(); }@Overridepublic void run() {System.out.println(Thread.currentThread().getName() + "嘗試獲取鎖");try {lock.lockInterruptibly();try {System.out.println(Thread.currentThread().getName() + "獲取到了鎖");Thread.sleep(5000);} catch (InterruptedException e) {System.out.println(Thread.currentThread().getName() + "睡眠期間被中斷了");} finally {lock.unlock();System.out.println(Thread.currentThread().getName() + "釋放了鎖");}} catch (InterruptedException e) {System.out.println(Thread.currentThread().getName() + "獲得鎖期間被中斷了");}} }
